ABSTRACT

A device for packaging and dispensing a cosmetic product prepared by mixing a first and a second bulk comprises: a bottle defining a bottle reservoir containing the first bulk; a cartridge defining a cartridge reservoir containing the second bulk and comprising a seal, the cartridge being arranged between a disassembled configuration and a mounted configuration; a seal opening mechanism adapted to open the seal in the mounted configuration, the bottle reservoir and the cartridge reservoir being in fluid communication in the mounted configuration; and a dispensing apparatus. The cartridge comprises a removable cartridge-sealing plug designed to cover the seal in the disassembled configuration and being replaced with the bottle in the mounted configuration.

The present invention relates to a device for packaging and dispensing a cosmetic product prepared by mixing a first and a second bulk, of the type comprising:

-   -   a bottle defining a bottle reservoir designed to contain the         first bulk, the bottle reservoir extending along a bottle axis         between a bottle upper end and a bottle lower end of the bottle;     -   a cartridge extending along a cartridge axis between a cartridge         upper end and a cartridge lower end, the cartridge defining a         cartridge reservoir designed to contain the second bulk, the         cartridge comprising a seal sealing the cartridge reservoir, the         cartridge being arranged between a disassembled configuration in         which it is spaced away from the bottle and a mounted         configuration in which it is mounted on the bottle;     -   a seal opening mechanism adapted to open the seal when the         cartridge is placed in the mounted configuration, the bottle         reservoir and the cartridge reservoir being in fluid         communication in the mounted configuration; and     -   a dispensing apparatus for dispensing the first bulk or the         cosmectic product from the bottle reservoir, the dispensing         apparatus being mounted on the bottle upper end of the bottle.

Such a device is intended to be used by a user to dispense a cosmetic product, for example, on a body surface.

Such a device enables a user to prepare a specific cosmetic product using specific bulks according to his wishes. For example, different bulks contained in different cartridges offer the user numerous customized blending possibilities.

The cosmetic product is for example, a cosmetic care product, a dyeing product or make-up product for the body surface. It is particularly in the form of a liquid or a gel.

More generally, a cosmetic product is a product as defined in EC Regulation No. 1223/2009 of the European Parliament and the Council of Nov. 30, 2009, relating to cosmetic products.

WO 2018/206898 A1 discloses a device for mixing two cosmetic products, the device comprising a bottle defining a first reservoir containing the first product, a cartridge defining a second reservoir containing the second product, the cartridge being mountable on the bottle, a seal sealing the first reservoir and a seal opening mechanism to perforate the seal during the mounting of the cartridge on the bottle.

It can be difficult for a user to properly place and replace a cartridge on a bottle without, for example, spilling or degrading the bulk of either the bottle or the cartridge.

One purpose of the invention is to provide a device that is easy to use and in which the bulks are safely packaged, so that the prepared cosmetic product presents optimal cosmetic properties.

For this purpose, the invention relates to a device of the aforementioned type, wherein the cartridge comprises a removable cartridge-sealing plug, the removable cartridge-sealing plug being designed to cover the seal in the disassembled configuration, the removable cartridge-sealing plug being replaced with the bottle in the mounted configuration.

The removable cartridge-sealing plug accounts for an additional sealing means that prevent any leaking of the second bulk outside the cartridge reservoir or any intrusion of air within the cartridge reservoir when the cartridge is, for example, in a disassembled configuration. The cartridge can thus be stored without any risk that the second bulk may be deteriorated. Furthermore, when the cartridge has been used, the removable cartridge-sealing plug makes it possible to seal again the cartridge reservoir so that residual cosmetic product is not spilled outside of the cartridge.

The device can have the following feature:

-   -   the bottle comprises a lower threaded neck at its bottle lower         end, the cartridge comprising a threaded outer tubular sleeve         extending along the cartridge axis towards the bottle, the lower         threaded neck and the threaded outer tubular sleeve being         designed to be screwed during the mounting of the cartridge on         the bottle.

Mounting by screwing is an efficient and safe way to fasten the bottle and the cartridge.

According to alternatives:

-   -   the cartridge comprises an inner tubular sleeve extending along         the cartridge axis and a lower wall, the inner tubular sleeve,         the lower wall and the seal defining the cartridge reservoir;     -   the lower wall is movable between a lower position in which the         cartridge reservoir has a first volume and an upper position in         which the cartridge reservoir has a second volume, the first         volume being greater than the second volume;     -   the cartridge comprises an injection mechanism for injecting the         second bulk within the bottle reservoir in the mounted         configuration, the injection mechanism comprising a button for         pushing the movable lower wall towards its upper position.

The presence of an injection mechanism enables the user to force the mixing of the first and the second bulk to prepare the cosmetic product. The push button accounts for an easy to use and efficient mechanical system. The lower wall acts as a piston that pushes the second bulk towards the bottle reservoir.

According to other alternatives:

-   -   the seal comprises a cylindrical skirt covering at least a         portion of an outer surface of the inner tubular sleeve;     -   the seal opening mechanism comprises a cutting edge designed to         open the seal when the cartridge is placed in the mounted         configuration;     -   the seal is movable with regards to the cutting edge between a         first sealed position in which the seal seals the cartridge         reservoir and a second open position in which the bottle         reservoir and the cartridge reservoir are in fluid         communication, by passing the cartridge between the disassembled         configuration and the mounted configuration;     -   the seal opening mechanism is borne by the cartridge;     -   the bottle lower end comprises a lower support portion designed         to cooperate with the seal during the mounting of the cartridge         on the bottle, so that the seal is pushed towards its open         position.

The seal opening mechanism being borne by the cartridge makes it possible for the user to manipulate a lightweight bottle. The mounting of the cartridge on the bottle leads to the opening of the seal. Therefore, the seal is easily open thanks to simple manipulation of the device.

In another variant, the dispensing apparatus comprises an extended portion extending within the bottle reservoir substantially along the bottle axis, the seal opening mechanism comprising a lower pushing end of the extended portion, the lower pushing end being designed to open the seal during mounting of the cartridge on the bottle.

The seal opening mechanism being part of the dispensing apparatus of the bottle makes it possible to implement a lightweight device in which the bottle and the cartridge have a simple structure without specific seal opening means such as, for example, the specific cutting edge.

In another variant, the dispensing apparatus is a pipette.

The pipette is a dispensing apparatus that can be easily used by the user in order to withdraw cosmetic product from the bottle reservoir and in order to dispense the cosmetic product on, for example, a body surface.

According to another alternative, the device further comprises a removable bottle-sealing plug designed to seal the bottle lower end of the bottle in the disassembled configuration, the removable bottle-sealing plug being replaced with the cartridge in the mounted configuration.

The removable bottle-sealing plug also accounts for a sealing means that prevent any leaking of either the first bulk or the cosmetic product and any intrusion of air within the bottle reservoir when the cartridge is, for example, in a disassembled configuration.

According to another alternative, the first bulk is a liquid and the second bulk is a powder.

The device offers a wide range of mixing possibilities. Various chemicals in various state of matter can be used to prepare, for example, a customized cosmetic product that is adapted to the wills of a user.

According to another alternative, the device comprises at least an auxiliary cartridge, the auxiliary cartridge defining an auxiliary cartridge reservoir designed to contain an additional second bulk, the auxiliary cartridge reservoir extending along an auxiliary cartridge axis between an auxiliary cartridge upper end and an auxiliary cartridge lower end of the auxiliary cartridge, the auxiliary cartridge comprising an auxiliary seal sealing the auxiliary cartridge reservoir, the auxiliary cartridge being arranged between a disassembled configuration in which it is spaced away from the bottle and a mounted configuration in which it is mounted on the bottle, the seal opening mechanism being adapted to open the auxiliary seal when the auxiliary cartridge is placed in the mounted configuration, the bottle reservoir and the auxiliary cartridge reservoir being in fluid communication in the mounted configuration, the auxiliary cartridge being able to be mounted on the bottle in replacement of the cartridge, the auxiliary cartridge advantageously comprising a removable auxiliary cartridge sealing plug, the removable auxiliary cartridge sealing plug being designed to cover the auxiliary seal in the disassembled configuration, the removable auxiliary cartridge sealing plug being replaced with the bottle in the mounted configuration.

Several cartridges can successively be mounted on a same bottle to, for example, adjust the quantity of the second bulk in the final cosmetic product.

The invention will be easier to understand after reading the following description, provided solely as an example and with reference to the appended drawings, in which:

FIG. 1 is a sectioned view of the device according to the invention, illustrating a sectioned view of a bottle and a cartridge, the cartridge being in a disassembled configuration;

The cutting edge 90 defines for example a helix around the cartridge axis C.

The annular junction 72 extends from the outer surface of the inner tubular sleeve 70 to the inner surface of the outer tubular sleeve 68 in a plane radial with regards to the cartridge axis C.

The annular junction 72 connects the outer and inner tubular sleeves 68, 70.

The annular junction 72 divides the cylindrical cartridge cavity 84 into an upper cylindrical cartridge cavity extending above the annular junction 72 and a lower cylindrical cartridge cavity extending below the annular junction 72.

The outer tubular sleeve 68 comprises a lower portion that delimits the lower cylindrical cartridge cavity and an upper portion that delimits the upper cylindrical cartridge cavity. The upper portion of the outer tubular sleeve 68 comprises the cartridge thread.

The lower wall 74 extends within the cylindrical inner cavity 88 transversally with regards to the cartridge axis C and seals the cylindrical inner cavity 88 at its lower end.

The seal 76 comprises a sealing round portion 96, a cylindrical skirt 98 and an annular abutment collar 100. The seal 76 seals an upper end of the inner tubular sleeve 70. The seal 76 seals the cylindrical inner cavity 88 from an upper end.

The sealing round portion 96 extends in a plane radial with regards to the cartridge axis C. It closes the seal upwardly.

The cylindrical skirt 98 extends along the cartridge axis C and covers at least a portion of the outer surface of the inner tubular sleeve 70.

The annular abutment collar 100 extends from the cylindrical skirt 98 radially towards the outer tubular sleeve 68 in the annular space between the inner tubular sleeve 70 and the outer tubular sleeve 68. It is designed to cooperate with the bottle lower end 24 as it will be described further below.

The inner tubular sleeve 70, the lower wall 74 and the seal 76 define a cartridge reservoir 102.

The cartridge reservoir 102 is designed to contain the second bulk.

The seal 76 is movable along the cartridge axis C in relation to the inner tubular sleeve 70, for opening the sealing round portion.

Thus, the seal 76 is movable with regards to the cutting edge 90 between a first sealed position in which the seal 76 seals the cartridge reservoir 102 and a second open position in which the bottle reservoir 28 and the cartridge reservoir 102 are in fluid communication. Here, the seal 76 is frangible and is configured to be broken by the cutting edge 90.

The cartridge 14 is arranged between a disassembled configuration in which it is spaced away from the bottle 12 and a mounted configuration in which it is mounted on the bottle 12.

The lower threaded neck 30 of the bottle 12 and the threaded outer tubular sleeve 68 of the cartridge 14 are designed to be screwed during the mounting of the cartridge 14 on the bottle 12.

The annular abutment collar 100 of the seal 76 is designed to cooperate with the lower support portion 44 of the bottle 12 during the mounting of the cartridge 14 on the bottle 12 so that the seal 76 is pushed towards its open position.

The removable cartridge-sealing plug 62 is designed to cover the seal 76 in the disassembled configuration.

The removable cartridge-sealing plug 62 is replaced with the bottle 12 in the mounted configuration.

The removable bottle-sealing plug 22 is replaced with the cartridge 14 in the mounted configuration.

The removable cartridge-sealing plug 62 comprises a cartridge-covering round wall 110 and a straight tubular skirt 112.

The straight tubular skirt 112 protrudes perpendicularly to the cartridge-covering round wall 110.

The tubular mounting sleeve 134 comprises a mounting sleeve thread. The mounting sleeve thread is complementary to the upper thread of the bottle upper end 26.

The wiper 136 comprises an upper collar 172 and a lower collar 174.

The upper collar 172 is designed to cooperate with the circular mounting protrusion of the tubular wall 20 so as to attach the wiper 136 and the tubular wall 20.

The upper collar 172 comprises an upper support surface 176.

The lower collar 174 extends inwardly towards the dispensing apparatus axis D and is also designed to extends towards the bottle axis B.

The lower collar 174 is designed to wipe any residual first bulk of cosmetic product that would remain on an outer surface of the conduit of the extended portion 132.

The dispensing apparatus 16 is arranged between a withdrawing configuration in which it is mounted on the bottle upper end 26 and a dispensing configuration in which it is spaced away from the bottle upper end 26.

The dispensing apparatus 16 and the bottle 12 are designed to be screwed together during the mounting of the dispensing apparatus 16 on the bottle 12.

In the withdrawing configuration, the outer annular retaining extension 148 of the handling portion 130 is abutted on the upper support surface 176 of the wiper 136.

In the withdrawing configuration, the first bulk or the cosmetic product can be withdrawn through manipulation of the handling portion 130.

In the dispensing configuration, the first bulk of the cosmetic product can be dispensed through manipulation of the handling portion 130.

The dispensing apparatus 16 is, for example, a pipette.

The seal opening mechanism 18 is adapted to open the seal 76 when the cartridge 14 is placed in the mounted configuration. The bottle reservoir 28 and the cartridge reservoir 102 are in fluid communication in the mounted configuration.

As illustrated in FIGS. 1 to 3 , the seal opening mechanism 18 is, for example, borne by the cartridge 14.

The seal opening mechanism 18 comprises the cutting edge 90 of the cartridge 14.

The cutting edge 90 is designed to open the seal 76 when the cartridge is placed in the mounted configuration. In particular, the cutting edge 90 is designed to perforate the seal 76 during the screwing of the cartridge 14 on the bottle 12.

The injection mechanism 64 is designed to inject the second bulk within the bottle reservoir 28 in the mounted configuration so that the first and second bulks are mixed to form the cosmetic product.

Advantageously, the device 10 further comprises at least an auxiliary cartridge (not shown).

The auxiliary cartridge is structurally identical to the cartridge described above. The auxiliary cartridge reservoir of the auxiliary cartridge comprises, for example, the second bulk or a third bulk different than the second bulk.

The auxiliary cartridge is able to be mounted on the bottle 12 in replacement of the cartridge.

The use of the device 10 for preparing and dispensing a cosmetic product will now be described.

With reference to FIG. 1 , a device 10 as described above is provided. The cartridge is in its disassembled configuration. The removable bottle-sealing plug 22 is in its covering configuration. The removable cartridge-sealing plug 62 is in its covering configuration. The dispensing apparatus 16 is in its withdrawing configuration. The seal 76 is in its closed configuration. The piston 116 is in its lower position.

The removable cartridge-sealing plug 62 is unscrewed from the structural portion 60 of the cartridge 14 so as to be put in its uncovering configuration.

The removable bottle-sealing plug 22 is unscrewed from the tubular wall 20 of the bottle so as to be put in its uncovering configuration.

The cartridge 14 is then screwed on the lower threaded neck 32 of the bottle 12 so as to be put in its mounted configuration.

During the mounting of the cartridge 14 on the bottle 12, the lower support portion 44 of the bottle lower end 24 pushes downward on the annular abutment collar 100. This leads to displacing the seal 76 along the cartridge axis C and to the breaking of the seal 76, in particular of the sealing round portion 96. The cylindrical skirt 98 of the seal 76 is displaced downward along the inner tubular sleeve 70 along the bottle axis B and the cartridge axis C.

The button 118 is pushed so as to be put in its upper position.

The first and second bulks are mixed. They form the cosmetic product.

The handling portion 130 is manipulated so as to withdraw cosmetic product from within the bottle reservoir 28 into the conduit of the extended portion 132.

The dispensing apparatus 16 is then unscrewed from the bottle 12 so as to be put in its dispensing configuration.

The handling portion 130 is manipulated so as to dispense cosmetic product from within the conduit of the extended portion 132 on, for example, a body surface of a user.

Thanks to the present invention, the first bulk and the second bulk are conditioned safely and optimally. Thanks to this device, a user can prepare a customized cosmetic product according to his wishes with bulks that have been protected from any degradation. In particular, the present invention prevent any intrusion of air within the cartridge reservoir so that the active ingredients within it are protected.

The present device is easy to use since all the steps required are based, for example, on screwing and unscrewing actions.

According to a second embodiment of the invention, illustrated on FIG. 4 , the seal 76 is removably attached to the inner tubular sleeve 70. The seal 76 is not frangible.

In particular, the inner tubular sleeve 70 comprises an annular sealing depression 180. The seal 76 comprises an annular sealing protrusion 182 designed to engage with the annular sealing depression 180, so as to secure the seal 76 with the inner tubular sleeve 68.

In this second embodiment, the button 118 is also the piston 116. The peripheral annular recess 124 of the button 118 is designed to cooperate with the inner surface of the inner tubular sleeve 70 when the button 118 is pushed up by the user. The inner surface of the inner tubular sleeve 70 therefore guides the button 118 when it is pushed by the user.

The seal opening mechanism 18 comprises a lower pushing end 186 of the extended portion 132 of the dispensing apparatus 16. The lower pushing end 186 is designed to open the seal 76 during the mounting of the cartridge 14 on the bottle 12. The lower pushing end 186 is defined on the extended portion lower end 156 of the extended portion 132 of the dispensing apparatus 16. The lower pushing end 186 is, for example, defined, on the tip of the pipette.

In particular, during the mounting of the cartridge 14 on the bottle 12, the lower pushing end is designed to push the seal 76 downwards, so that the annular sealing protrusion 182 disengages with the annular sealing depression 180. The seal 76 is then free to move with regards to the inner tubular sleeve 70 and is put in its open position. The bottle reservoir 28 and the cartridge reservoir 102 are then in fluid communication.

According to the second embodiment of the invention, the circular mounting protrusion 40 extends radially towards the bottle axis B from the bottle upper end 26.

According to a variant, the second bulk is a liquid.

According to a variant of the first and second embodiments of the invention, the cartridge does not comprise any piston. The cartridge reservoir 102 is then defined by the inner tubular sleeve 70, the seal 76 and a fixed lower wall.
